There is no AA in any version of the game. However, there are solutions for aliased edges. Firstly, the edge blurring and secondly, temporal AA. Basically, this method uses the information of a previously rendered frame to filter the aliasing. Edge AA is pretty straight forward though, it just blurs the edges where possible.
The reason for this is the way they do Deferred lighting. Using hardware anti-aliasing would be much too expensive. Unthinkably expensive on the hardware. So, that went out the window.
Fear not, from the screenshots and footage that I've seen, these two methods do a pretty good job at removing aliasing. Actually, a very good job. It's not comparable to 16x MSAA, but it's nearly identical to 4x MSAA. That's pretty good, if you ask me.
